The term 'attack from all directions' can be summarized by two crossword solutions: SIEGE and BESET. SIEGE is a military tactic in which an attacking force surrounds a fortified position and blocks all access to it, usually with the intent of forcing the defenders to surrender. BESET is a similar tactic, but instead of surrounding the target, the attackers come from all directions at once. Both tactics are used to overwhelm the defenders and gain a decisive victory.
